AirFit N30i Nasal CPAP Mask

SKU63819 63817

The innovative N30i features a top-of-head tube design that gives you the freedom to sleep in any position. And the curved nasal cradle cushion with QuietAir™ technology sits comfortably under your nose, making it easy to sleep on your side or stomach, and enjoy a quiet night’s sleep. With no front-end tube, the mask stays out of sight and out of the way. The mask is specially designed to slide quickly on and off to make your bedtime routine easier. The quick-release elbow makes it easy to disconnect the mask from tubing if you need to get up at night. (Available in Standard or Small frames; both include Small, Medium and Small-Wide cushions)

AirFit N30i – ResMed’s most adaptable mask to date

The AirFit N30i from ResMed is an under-nose mask. This makes it easier to seal; a smaller contact area means less risk of leakage. The minimal-contact design gives you the freedom to move into any sleeping position comfortably.

The N30i is one of the latest in the AirFit range of nasal masks but has little in common with the masks before. As well as using an under-nose cushion, the CPAP tubing now connects on the drop of the head rather than the front of the mask. This significantly improves your freedom, with the tubing far less likely to be pulled when changing position. It also reduces the weight of the front of the mask, reducing the effects of gravity when sleeping on your side.

The N30i frame is flexible (on most masks, this is rigid), allowing a degree of automatic adjustment throughout the night. Every aspect of the AirFit N30i’s design focuses on patients who change position regularly or spend most of the night on their side. The AirFit N30i’s flexibility, and hose positioning, are particularly beneficial for those who frequently move in sleep.


Sizing your ResMed AirFit N30i

There are two starter packs, each of which is delivered with 1 frame and 1 cushion as follows:

  • Small starter pack: 1 small frame and 1 small cushion
  • Standard starter pack: 1 standard frame and 1 standard cushion

Please note: the standard frame is bigger than the smaller frame. Generally, most men should select the standard frame, and most women should choose the small one. See below for more information on this.

Additional cushions can be ordered as spare parts:

  • Small wide cushion (SW size): for small, flat noses
  • Wide cushion (W size): for large, flat noses

Please note that these cushions must be purchased separately if required; ResMed does not include them as standard. See the guides below for more information about sizing.


Sizing your ResMed AirFit N30i frame

Step 1 – In general, men should select the standard frame size, and women should select the small frame size. These general recommendations can be disregarded if you feel you have a smaller/larger face than average.

Step 2 – The frame should sit on the top of the head, like a headband. If the frame is too small, it will feel tight and sit too close to your forehead. If the frame is too large, it will feel loose and sit too far back on your head.

Cushions are also available in Small Wide (for small flat noses), and Wide (for large flat noses). Should one of these additional sizes be required, it can be ordered here – they will automatically be half-price when ordered at the same time as the N30 itself. Use the guide below to determine if you need one of the additional sizes.


Sizing your ResMed AirFit N30i cushion

Step 1 – Download the Sizing Guide by clicking here. Print it in the right dimensions (check the scale).

Step 2 – Place the template below your nose, perpendicular to your face. If you have a narrow nose, start with the blue/red side of the template. If you have a wide nose, start with the black/purple side of the template.

Step 3 – Look into a mirror and assess whether your nose falls inside or outside the margins on the template. If you are between two sizes, choose the larger one.

Step 4 – If your nose is size S (red) or M (blue), select the appropriate cushion from your starter pack. If your nose is SW (purple) or W (black), then you will need to order the cushion in addition to a starter pack; ResMed does not include these as standard with either pack.
